[0029] Currently, some devices that require unlocking of vehicle body locks involve the use of power units, and the hydraulic cylinder lifting device is widely recognized in the industry for unlocking some vehicle body locks.

[0030] The hydraulic cylinder lifting device mainly consists of an electric pump, control valve, oil pipes, cylinder, wiring harness, and other components. Its working principle is as follows: the electric pump is connected to the power source via the wiring harness, thereby controlling the pump's operation; the control valve controls the high-pressure oil, which enters the cylinder through the oil pipe, driving the cylinder piston rod to perform lifting and lowering movements.

[0031] However, hydraulic cylinder lifting devices have many drawbacks. Their complex structure leads to high manufacturing costs; their lifting force is relatively small, making them unsuitable for scenarios with high lifting force requirements; they are prone to malfunction in low-temperature environments; and they are prone to oil leakage, requiring regular maintenance and causing environmental pollution.

[0032] To address the aforementioned technical problems, this application provides an alternative solution. Figure 1 This is a schematic diagram of a vehicle body lock unlocking device provided in an embodiment of this application; Figure 2This is a cross-sectional structural diagram of a vehicle body lock unlocking device provided in an embodiment of this application; Figure 3 This is a schematic diagram of the structure of the motor provided in the embodiments of this application; Figure 4 for Figure 2 A structural diagram from another perspective.

[0033] Reference Appendix Figures 1-4 As shown, this application provides a vehicle body lock unlocking device, including a first housing 100, a motor 200, and a displacement assembly 300. The motor 200 controls the displacement assembly 300 to move back and forth. The displacement assembly 300 includes a pull cable bend 310 and a first shaft 320. One end of the pull cable bend 310 is connected to the outside of the first housing 100, and the other end of the pull cable bend 310 is connected to the first shaft 320. The first shaft 320 extends outward and has a lock head on one side of its end. The pull cable bend 310 has a receiving cavity. A first line is provided on the side of the lock head near the first shaft 320. The first line passes through the first shaft 320 and the pull cable bend 310 and is connected to the motor 200. The motor 200 rotates to drive the lock head to reciprocate to open and close the lock.

[0034] It should be noted that in the vehicle body lock unlocking device, the motor 200 controls the displacement component 300. The rotation of the motor 200 drives the lock head to move. It is important to clarify that the cable bend 310 contains a component that can change the movement trajectory of the lock head. This component can be a pulley or other parts capable of altering the movement trajectory; this application does not specify a particular component. The rotation of the motor 200 drives the lock head to move back and forth to achieve the purpose of opening and closing the lock. The power of the motor 200 can be effectively transmitted, providing sufficient force for opening and closing the lock, meeting the unlocking force requirements of the vehicle body lock in actual use.

[0035] Because the vehicle lock unlocking device is electrically controlled, compared to traditional hydraulic cylinder control devices, this device can operate normally in high and low temperature environments ranging from -50 degrees Celsius to 80 degrees Celsius.

[0036] In this application, the lock head is controlled by the motor 200 and can be displaced within a certain range. In this application, the first shaft 320 adopts a flexible shaft structure. During the displacement of the lock head, due to the characteristics of the internal structure of the lock hole, the first shaft 320 is designed to be telescopic and bend at a certain angle. This allows the lock head connected to the end of the first shaft 320 to pass smoothly through the lock hole, avoiding frictional interference between the lock head and the first shaft 320 due to deviation from the original movement trajectory, which would lead to wear of the first line.

[0037] According to one embodiment of this application, a motor 200 is disposed inside a first housing 100, a displacement component 300 is disposed outside the first housing 100, and a connector is installed at the connection point between the pull wire elbow 310 and the outside of the first housing 100.

[0038] It should be noted that the end of the pull cable elbow 310 connects to the output end of the motor 200. The connecting parts installed in this connection include a threaded sleeve, a retaining sleeve, and a lock nut. The purpose of these connecting parts is to enhance the connection strength and stability between the two components. This ensures accurate response to the displacement commands of the motor 200 and prevents the pull cable elbow 310 from becoming loose due to pressure from the first wire during operation. A stable connection also reduces deviations in the lock head displacement distance caused by loose connections, ensuring that the vehicle body lock unlocking device maintains precise unlocking action over long-term use, thus improving the user experience.

[0039] According to one embodiment of this application, the motor 200 includes a reducer 210 and a reel 220, with the output end of the reducer 210 connected to the reel 220.

[0040] It should be noted that the reducer 210 provided in this application integrates a power supply. After the motor 200 responds to the unlocking command of the vehicle body lock, the power supply inside the reducer 210 starts and drives the reducer 210 to rotate. The rotation of the reducer 210 drives the reel 220 to rotate. After the reel 220 rotates, it further drives the extension of the first line to move up and down and laterally.

[0041] Furthermore, the reducer 210 converts the high speed of the power supply into a low speed, high torque output. During the unlocking process of the vehicle body lock, the larger torque allows the pulley 220 to more powerfully drive the first wire up and down, thereby easily driving the lock head and realizing the unlocking and locking actions of the vehicle body lock. It can overcome greater resistance and is suitable for scenarios with high requirements for unlocking force of the vehicle body lock, improving the practicality and reliability of the device.

[0042] According to one embodiment of this application, the displacement component 300 further includes a first line, the first line is wound on the reel 220, the pull line bend 310 is provided with a wheel axle, and the first line is hung on the wheel axle and connected to the lock head.

[0043] It should be noted that the first line in this application is hung on the spool 220. The rotation of the spool 220 also drives the first line to move. The movement of the first line in turn drives the lock head to move back and forth. It is particularly important to point out that the other end of the first line is hung on the connector. The connector plays a certain role in protecting the first line, and also plays the role in fixing the first line and improving the stability of the connection.

[0044] According to one embodiment of this application, a groove is provided on the side of the spool 220 away from the output end of the reducer 210, and at least two latches are provided on the side of the groove to restrict the rotation path of the spool 220.

[0045] It should be noted that a touch switch is installed on the latch at this location. When the reel 220 rotates to this position, it triggers an electrical signal to stop the motor, thereby stopping the reducer 210. In the vehicle body lock unlocking device, this allows for precise control of the displacement and position of the folding lock head, resulting in more accurate unlocking and closing actions. Each operation ensures the lock head accurately reaches the designated position, reducing unlocking and closing anomalies caused by rotational deviations, improving user experience and device reliability.

[0046] Furthermore, the latch restricts the rotation path of the spool 220, preventing instability such as wobbling or deviation during rotation. Over long-term use, this effectively reduces friction and collisions between the spool 220 and other components, lowering the risk of wear and damage, extending the lifespan of the spool 220, cable bend 310, and other related components, improving the stability and durability of the entire vehicle lock unlocking device, and reducing maintenance costs and frequency. It also prevents the spool 220 from rotating arbitrarily due to external interference or misoperation, thus preventing accidental unlocking.

[0047] According to one embodiment of this application, a baffle 240 is connected to the end of the spool 220 away from the reducer 210. The baffle 240 is partially bent to abut against the inner wall of the first housing 100. A limit switch is installed on the baffle 240, and the limit switch controls the working state of the spool 220.

[0048] It should be noted that the baffle 240 is fixedly connected to the reel 220 by bolts. On the one hand, it limits the movement of the first thread, preventing it from slipping off and running onto the outer ring of the reel 220 during operation. On the other hand, the portion of the baffle 240 connected to the reel 220 bends and abuts against the inner wall of the first housing 100, providing an additional support point for the reel 220. When the motor 200 drives the reel 220 to rotate, the contact between the baffle 240 and the inner wall of the housing effectively reduces the wobbling and axial displacement of the reel 220, making the reel 220 more stable during rotation.

[0049] In addition, the limit switch can be installed on one side of the baffle 240 before the spool 220 is installed. The limit switch is used to control the working state of the spool 220 and to record the start and end positions of the spool 220's rotation. By adjusting the position of the limit switch and cooperating with the buckle structure described above, the movement process of the spool 220 can be limited, which can further reduce the loss generated when the spool 220 drives the first line to move. This not only helps to improve the stability of the entire vehicle lock unlocking device, but also reduces the wear of components caused by the spool 220's shaking and extends the service life of the device.

[0050] According to one embodiment of this application, a first switch device 250 is installed on the upper end of the reducer 210, a touch component is provided on one side of the first switch device 250, and a through hole is opened on the side of the first housing 100 extending from the touch component, and a first cover 110 is installed at the through hole.

[0051] It should be noted that the first switch device 250 is located inside the first housing 100. The user can open the first cover 110 to operate the first switch device 250. After the first switch device 250 is started, the motor 200 needs to be manually operated to complete the unlocking and locking of the vehicle body lock, so as to avoid the situation of the vehicle body lock not being fully unlocked or over-unlocking, and improve the accuracy and stability of the vehicle body lock unlocking device.

[0052] Furthermore, the first housing 100 has a through hole on the side extending from the touch component and a first cover 110 is installed thereon, which can prevent external contaminants such as dust and moisture from entering the housing through the through hole. This not only protects the touch component and the first switch device 250 from failure due to contamination, but also prevents contaminants from affecting the normal operation of the motor 200 and the reducer 210, extending the service life of the device and ensuring that the vehicle body lock unlocking device can work stably in various environments.

[0053] According to one embodiment provided in this application, the first housing 100 further includes a first circuit board 400 and a second switch device 130. The second switch device 130 is mounted above the motor 200, and the first circuit board 400 is disposed above the second switch device 130 and controls the second switch device 130.

[0054] It should be noted that the second switch device 130 operates automatically after being triggered. After the second switch device 130 is raised, the first circuit board 400 receives the signal and sends a command to the motor 200. The reducer 210 inside the motor 200 rotates, driving the reel 220 to rotate, which in turn drives the first wire to unlock the car body lock. When the reel 220 rotates to the latch position, the reducer 210 stops moving and self-locks, completing the action command of unlocking the car body lock.

[0055] When the second switch device 130 is lowered, the first circuit board 400 receives a signal and sends a command to the motor 200. The reducer 210 drives the first wire to perform a locking operation. After the wire wheel 220 rotates to the buckle position on the other side, the reducer 210 stops moving and self-locks, completing the locking action command.

[0056] According to one embodiment of this application, one end of the second switch device 130 is provided with a contact extending outward, and the first housing 100 is provided with a second cover 120 on the side where the contact extends.

[0057] It should be noted that both the first cover 110 and the second cover 120 are located on the outside of the switch. Users need to open these covers to operate the switch. These covers effectively prevent dust, moisture, debris, and other external contaminants from entering the first housing 100. This avoids damage such as corrosion and short circuits to the contacts and internal circuitry of the switch, ensuring the switch is always in good working order, extending its service life, and thus guaranteeing the stable and reliable operation of the entire vehicle lock unlocking device.

[0058] According to one embodiment of the present application, the first housing 100 further includes a connector 500, one end of which extends into the interior of the first housing 100.

[0059] It should be noted that one end of the connector 500 extends into the interior of the first housing 100, providing a convenient electrical connection interface for the device. This connector allows for quick connection to external power supplies, control signal lines, etc. For example, in practical applications, it can easily connect to power lines to supply power to components such as the motor 200 and the first circuit board 400, and can also connect to external control devices to achieve remote or automated control of the vehicle body lock unlocking device, reducing wiring complexity and improving the stability and reliability of the electrical connection.
